If the heating installation operates overseveral floors, it may be necessary to have higher waterlevels on the pressure gauge.> Rotate the cap of the auto air vent (1) on the pump acouple of times to loosen it (the appliance is venti-lated automatically by the auto air vent during contin-uous operation).> Open all radiator valves in the installation.barbar1 234Fig. 6.2 Check the filling pressure of the heating installationi The ecoTEC units are supplied with a pressuregauge and a digital pressure display (2). Usingthe pressure gauge you can perform a quickcheck whether the filling pressure is withinthe prescribed range or not, even when theunit is switched off. With the unit switched on,you can read off the exact pressure by push-ing the minus button „-“.> Turn the rotary knobs (1) and (4) to the left hand stopand switch the unit on using the main switch (3).i Use the test programme P.6 for filling theheating system: The priority changeover valvemoves to the central position, the heatingpump is not running and the unit does not gointo heating mode, see Section 9.2.i To avoid running the system with too little waterand thus to prevent damage, your appliancehas a water pressure sensor. This signals thelow pressure level if the level falls below60 kPa (0.6 bar) by the water pressure value inthe display flashing. If the water pressure fallsbelow 30 kPa (0.3 bar) the unit switches off.The error message F.22 appears in the display.Fill the system up with water before you startup the appliance again.Filling the heating system:21Fig. 6.3 Filling the heating system
